NOVILLE, OF OLD BRIDGE, NEW JERSEY, ASSIGNOR TO THE KIN-AD-SCOPE C0., INC., OF NEVI YORK, N. Y., A `GORIEOR.YJION 10F NEW YORK CHANGEABLE SIGN Application led March 29, 1923. Serial No.. 628,594.y

This. invention relates to apparatus for simulating moving pictures, and is an improvement on the apparatus shown in my Patents #1,288,145 and 1,470,468.

The principal object of the present invention is to provide an improved means for constructing the translucent figure-carrying member.

Another object is to produce a device of this nature which shall he simple of construction, cheap to manufacture and highly eflicient for the purpose for which it is designed.

Vith these and other objects in view the invention resides in a certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly1 pointed out in the appended claims and are illustrated in the accompanying drawing, in which Figure 1 is a view of the rear figure-carrying element.

Figure 2 illustrates the means for neutralizing the front figure-carrying element.

Figure 3 illustrates the front figure-carrying element.

Figure 4 shows the combination of the means separately illustrated -in Figures l and 2.

Figure 5 shows the screen or iigurelcarrying device complete, and

Figure 6 is a sectional view taken of the device as shown in Figure 5.

Figures 7. 8 and 9 illustrate the invention as embodied in a modified form.

Like characters of reference refer to like parts in all views.

In my prior applications I have shown a screen or figure-carrying device consisting of a sheet of paper printed on both sides. However, in carrying the invention into praetical operation, it has been found difficult to have the sheets properly printed as the registry guide of a printing press is on the right hand side usually, and when the sheet is turned to print the reverse it has been very difficult to obtain a proper registry of the figures. The present invention contemplates the providing of means which eliminate this the device will show the ligure 14; and when factor of uncertainty and produce the perfectly matched and registered screen or figure-carrying device. Referringto the drawing in detail, 10 represents a sheet of translucent material such as paper having a figure 11 printed or otherwise impressed thereon in thesame or contrasting color and preferably opaque. Vhile in the drawings the letters A and B have been used to stand for the figures, it is to be unden .stood that this may be replaced by portraits, or advertising matter or any other suitable devices. l

12 represents a front sheet of translucent material which is preferably provided with background 13, and a contrasting figure or device 14... y Y y In Figure 2 is shown a sheet 15 upon which is printed a figure 16 which is of exactly the same size and shape as the figure 14 but of the same color as the background 13 g the baclground of member 15 being the same as the color of the figure 14. It will be seen that if the sheets 12 and lare matched with the figures in registry, then when a light passes through the sheets, no `figures will appear thereon and the sheets will appear to be of the uniform color of the background 13. In other words, sheet 15 would act as a mask for sheet 12. 80 In carrying the invention into practice sheet 15 is disposed of and the figure 16 is printed on the sheet 10 as shown in Figure 4. The front face of sheet 10 is then covered with gelatin or other adhesive and the back of sheet 12 is also covered with adhesive and the sheets 10 and 12 are placed together in a frame and light passed through them. It can then be seen if figure 16 is in proper registry with figure 14 or not, and the sheets are then moved relatively to each other until this effect is obtained. The sheets are then firmly pressed together producing the device shown in Figures 5 and 6. 95 It will be readily seen that by substituting this sheet for the translucent element or support l0 of my Letters Patent Number 1,470,- 468, the light when flashed on the front of dashed at the back of the screen Will show the figure 11.

In the modified form shown in Figures 7, 8 and 9, the front sheet is shown at 2O and includes a character or figure 21 and a background 22 of contrasting colors. The back sheet is shown at 23 and has a character 24 printed thereon and of the same color as the background 22. Printed on the back of sheet 2.0" is the second figure ,or character-.25. The sheets are held together by gelatin as inthe other case. The advantage in this method is that in printing, one has a clean White surface for each impression and may better judge the value thereof and that it is 'clean and perfeet.

Wrhat is claimed as nevv` is y 1. A changeable sign of the class described comprising a translucent colored vfront member having a plain translucent ligure thereon, a plain translucent backgroundl member haviner a translucent figure thereon of the same co or as said front member and registering with said irst mentioned ligure, so that when g illuminated lfrei-n the rear said igures are obliterated, anda differently shaped translucent ligure of another `color also on said ybackground member to be visibly projected against said front member when so illuminated.

2. A `device of the class described comprising a plain translucent back sheet having a colored character of a certain configuration thereon, a translucent colored front sheet havv ing thereon plain translucent character in register with the eharacter on back sheet, said characters being therefore invisible when said device is illuminated from the rear, and an opaque lcharacter on said back vsheet visible when so illuminated. l

In testimony whereof I have y ailixed my Signature CARL E NOVILLE.
